Casino Bonus Terms Explained: The Clauses That Matter
Casino bonus terms are long by design. The headline — '200% up to £500 + 100 Free Spins' — is prominently displayed; the clauses that define whether that offer has any real value are buried several scrolls below. This guide decodes the specific terms that actually determine whether a bonus is worth claiming, in the order you're most likely to encounter them.
In this guide
Maximum Cashout (Withdrawal Cap)
The maximum cashout clause sets an absolute ceiling on how much you can withdraw from bonus-derived winnings, regardless of how much you actually win.
This is one of the most financially significant terms in any bonus and one of the least prominent. A typical no deposit bonus might carry a £50 maximum cashout. If you land a £500 win during your bonus play, only £50 is accessible — the remaining £450 is forfeited. The casino is not hiding this; it is disclosed in the terms. But it is rarely emphasised in the promotional material.
Maximum cashout limits vary dramatically between operators. Some welcome bonuses cap withdrawals at £200–£500, which is reasonable relative to the bonus amount. No deposit offers routinely cap at £20–£50. A handful of casinos — particularly those targeting high-volume players — advertise 'unlimited withdrawal' bonuses with no cap, though these almost always carry higher wagering requirements to compensate.
What to look for: For deposit bonuses, a cashout cap lower than 5x the bonus amount is restrictive. For no deposit offers, any cap below £30 makes a meaningful win essentially unreachable in practice.
Game Contribution / Game Weighting
Not every game contributes equally toward clearing a wagering requirement. Casinos publish a game contribution table — sometimes called a game weighting schedule — in their bonus terms, and the differences between games are substantial.
Slots are almost universally set at 100% contribution. Every £1 wagered on a slot counts as £1 toward the requirement. This is why casinos typically restrict bonus play to slots by default.
Live casino and table games — roulette, blackjack, baccarat — frequently contribute between 0% and 20%. At 10% contribution, clearing a £1,000 wagering requirement on blackjack would require £10,000 in actual bets. At 0%, table games don't count at all.
Video poker is commonly excluded or set at 5%–10%.
Specific slot exclusions also exist. High-volatility or jackpot slots are sometimes excluded entirely from bonus play, or contribute at a reduced rate. If you intended to play a specific title — say, a Megaways slot with high max win potential — check it's not excluded before claiming the bonus.
The practical consequence: if you're not primarily a slots player, most casino bonuses offer you significantly less value than they appear to. The headline wagering figure assumes 100% contribution from all play.
The Maximum Bet Rule
The maximum bet rule is the most commonly violated bonus term, often accidentally. It states that while a bonus is active, you may not place a single bet above a specified amount — typically £5 per spin or per hand, sometimes as low as £2.
The purpose of the rule is to prevent players from betting their entire bonus balance on a single high-stake spin, which would either clear the wagering requirement in one go or lose everything instantly. From the casino's perspective, either outcome undermines the intended use of the promotion.
In practice, many players breach this rule without realising it. They deposit, receive a bonus, then play at their normal stake level without adjusting for the bonus restriction. Casinos are within their rights to void winnings — or in some cases entire balances — if the maximum bet rule is breached during bonus play.
This is not a hypothetical risk. Forums are full of players who won significant sums during a bonus session only to have the withdrawal refused because one or more bets exceeded the £5 cap. The rule applies to the entire period a bonus is active, even if you're betting with your own deposit funds simultaneously.
Practical advice: If you prefer playing at £10+ per spin, consider declining the bonus at the point of deposit. Most casinos allow you to opt out. Playing without a bonus gives you full freedom over your stake size and no withdrawal restrictions.
Bonus Expiry and Time Limits
Casino bonuses operate under two separate time constraints that players frequently confuse.
Activation deadline: The window in which you must trigger the bonus after it's credited — sometimes just 24–72 hours for free spins. Miss this and the spins expire unused.
Wagering deadline: The period within which you must clear the wagering requirement after the bonus is activated — typically 7 to 30 days. This is the more consequential deadline, because it determines whether you can realistically complete the playthrough at sensible stake levels.
A 30x wagering requirement on a £100 bonus = £3,000 total wagering. Over 30 days, that's £100/day. At £1 per spin on a medium-volatility slot, you'd need to play around 100 spins per day — achievable for a regular player but demanding if you have other commitments.
Tighter deadlines — 7 days for the same requirement — compress that to £429/day, which at sensible stakes is only realistic for heavy players. If you can't comfortably complete the wagering within the timeframe at stakes you're comfortable with, it's better not to claim the bonus at all.
When a bonus expires uncompleted, both the bonus funds and any associated winnings are removed. Your real-money deposit balance is unaffected.
Sticky vs. Non-Sticky Bonuses
This distinction is important and poorly understood outside experienced player communities.
A non-sticky bonus (also called a 'cashable' bonus) is separate from your real-money balance. When you deposit £100 and receive a £100 non-sticky bonus, you have two distinct pots. You play through the wagering requirement, and once met, your real-money deposit is fully withdrawable alongside any net winnings. The bonus amount itself may or may not be withdrawable depending on the specific terms — but your original deposit is always safe.
A sticky bonus (also called a 'non-cashable' or 'phantom' bonus) is different. It is added to your balance and used for wagering, but it is never withdrawn — it simply disappears when you cash out. You receive a sticky bonus of £100 on a £100 deposit, run your balance up to £350 through play, and withdraw: you keep £250 (the £350 minus the £100 sticky bonus). The bonus amplified your balance and gave you more wagering capacity, but it was never yours to withdraw.
Neither structure is inherently better — they suit different playing styles. Non-sticky bonuses offer more downside protection (your deposit is preserved). Sticky bonuses give you more leverage for high-variance play, where you're specifically targeting a large win.
